- Brockton, in the. county-6f Plymouth and State of Massachusetts, haveinvented an Improvement in I-IeelSeat Trimmers for Pat- ;ent-Leather, ofwhich the following descrip- -'-gua;rd:'sfo that'it can turnvery'slowly'with re- A tion; in connection with the accompanyingdrawings, is a specification, likeletters onthe a1 fdrawingsrepresenting like parts.

I have found that bymounting thecrease tion-'t the-ra' idly rotatingcutter of a heel seat trimmfielris aver, or the like, and applying. athin of oil thereto, greatly superior results follow, especially withpatent leather,

and accordingly y invention resides in'the provision ofsaid mechanism. f

In the drawings, in which I- have, shown my invention applied to ausuaikindof heel seattrimmer, I have shownthe machine in sideielevationy1 A driving shaft 1 of the-trimmer is jour-- naled at the upper end2 ofa suitable standard 3. The shaft and trimmer are driven by a b pu ey 4and-belt5, 1

'The rotary trimmer knife is indicated at 6 1 in position to operate; ona heel seat 7 of a "30* I a crease guard 10 to travel in the rand-creaseshoe8.

Opposite thefinger guard 9 I mount loosely f the shoe and guide thecutter in its Work,

and above said guard 10 I place a frictional retardin device, shownasa'block 11 -suspended 0m a bracket 12 clamped inposition'by' a thumbscrew 13-; -said block con- I taining absorbent material connected, by aA 12 and provided i block 11, a suppl suitable materia v p to a 17,which is preferably mounted tube 14, preferably of copper, to thebracket with a va ve 15 for regulat-. ing the passage of the oil to the;absorbent tube 16 of rubber or other leading from the bracket on thewallor in. any other-position above the machine to give a considerablehead to thefflow of oil, said tank being controlled, by av lve'18. 1 f in-pra'ctice, the retarding oilin'gblock 11 I prevents the rapid rotationof the-fguard wheel or plate 10 and, at the same-time maintains thebeveled surface'o'f'the leather coate ed witha thinfilm ofQiI-sothatjsaid guard 10 travels very slowly withits oil-smeared S111?face in contact with the upper leather. The resultis that the operatorcan trim the heel seat with the rotary-cutterfiat-the highest speedWithout the slightest danger of injury tothe shoe, eitherby leaving'anycrease'on fthe upperleather or'by burning it or even dulling the finishin case it is patent leather.- I am aware thatoil has been usedheretofore and accordingly I do not claim the same broadly, vmyinvention being restricted to t'he particular application thereof andcombination of parts above described and "hereinafter claimed; r',I-Iav'ing described my'inv'ention, What I claim asnew and desire tosecure by Letters I Patent,is, I a y In a machine of' the kinddescribed, a v rotary cutter, high speed driving means there v for, aslow speedguard plate mounted at one end of said cutter for traveling inthe rand crease, and 'aicombined retarder and., oiler for restrictingthe movement of said '75 guard plate-and at the same time maintainingthe outer surface thereof continuously smeared with oil.

In testimony whereof I have'signed my; 'name to this specification, inthe presence of .twq'subscribing Witnesses;-
